Kahr Laserlyte Gunsight Questions

Laserlyte recently discontinued a laser sight that replaced the factory rear sight. Has anyone had any experience with it? It seemed like a good option for someone that wants to add a laser sight, but to keep using Kahr's factory grips. I currently have a K9. For me, the only other laser sight option is replace the factory grips with a Crimson Trace set.

By the way, the LaserLyte Kahr gunsite was manufactured only for Kahr's newer rear sight dovetails.
